Abstract

The utility model relates to a reciprocating planer which comprises a planer body (11), a ram (9), a worktable (19) and a speed change mechanism. The utility model is characterized in that a rocker arm mechanism is composed of a driving gear (6), a rocker arm wheel (7), a rocker arm (10) and a connection rod (8) for the rocker arm, and a feed mechanism is composed of a transmitting gear (12), a cam (13), a push rod (15), a roller (14), a ratchet wheel (17), a pawl frame (16) and a pawl (18). A base plate (5) of a knife frame is provided with a front clapper and a rear clapper which are respectively provided with a knife clipping base. The utility model improves the rocker arm mechanism, the feed mechanism and a planing knife.

Description

Recipocating planer

The utility model relates to a kind of reciprocating planer.

Present planer is a shot, flogs a dead horse during the planing tool backhaul, and operating efficiency is lower.

The purpose of this utility model is to provide a kind of planing tool reciprocating planer of workpiece of can both planing in round trip.

The utility model comprises lathe bed, ram, workbench, gear, it is characterized in that: rocker arm body is made up of driven wheel, rocking arm wheel, rocking arm and rocker-arm link; the rocking arm wheel is fixed on the driven wheel; rocking arm one end is connected on the lathe bed; the other end links to each other with ram, between rocking arm and the rocking arm wheel rocker-arm link is arranged; Feed mechanism is made up of travelling gear, cam, push rod, roller, ratchet, ratchet holder and ratchet, the driven wheel engagement of travelling gear and rocker arm body, travelling gear is provided with cam, between ratchet holder and the cam push rod is arranged, this push rod one end is connected on the ratchet holder, the other end has roller, and said roller withstands on the cam; Tool rest carriage is provided with former and later two clappers, all is provided with the folder tool rest on the forward and backward clappers, and the cutter branch on two clappers is on two straight lines identical with direction of feed.

For in use reducing the time of changing cutter, can adapt to the different workpiece that require of planing simultaneously again, said folder tool rest is preferably square clamping plate, and a folder mouth that clamps planing tool is respectively arranged on four angles of these clamping plate.

The utility model has been done improvement to rocker arm body, feed mechanism and knife rest, make the planing tool workpiece of in round trip, can both planing, mechanical efficiency and planing cutting speed have been improved greatly, owing to adopt square multitool holder, need not frequently change cutter when making the different workpiece that requires of planing, need only change getting final product, easy to use, save time.

Below in conjunction with accompanying drawing the utility model and embodiment are described in detail.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the knife rest schematic diagram of the utility model embodiment 1.

Fig. 3 is the knife rest schematic side view of the utility model embodiment 2.

Fig. 4 is the knife rest front elevational schematic of the utility model embodiment 2.

With reference to Fig. 1, the utility model comprises lathe bed (11), ram (9), workbench (19) and gear; rocker arm body is made up of driven wheel (6), rocking arm wheel (7), rocking arm (10) and rocker-arm link (8); rocking arm wheel (7) is fixed on the driven wheel (6); an end of rocking arm (10) is connected on the lathe bed (11); the other end is connected with ram (9); between rocking arm wheel (7) and the rocking arm (10) rocker-arm link (8) is arranged, the gears engaged of driven wheel (6) and gear; Feed mechanism is made up of travelling gear (12), cam (13), push rod (15), roller (14), ratchet (17), ratchet (18) and ratchet holder (16), travelling gear (12) meshes with the driven wheel (6) of rocker arm body, the number of teeth is identical with driven wheel (6), be connected with a cam (13) on the travelling gear (12), between ratchet holder (16) and the cam (13) push rod (15) is arranged, these push rod (15) one ends are connected in the rear end of ratchet holder (16), and the other end is provided with a roller (14) and withstands on the cam (13).Respectively be provided with a clapper box (4) before and after the planker of knife rest (5), be equipped with clappers and folder tool rest (3) on two clapper boxs, cutter (1) branch on two clappers is on two straight lines identical with direction of feed.In the work; rocking arm wheel (7), rocker-arm link (8) drive rocking arm (10); make ram (9) produce the identical rectilinear motion of reciprocal scanning frequency; when advancing forward; the in running order cutting workpiece of cutter the preceding; after cutter lift and tow; during backhaul; the in running order cutting workpiece of the cutter behind planker; cutter then lifts and tows the preceding; because the cutter on the clappers of front and back is in respectively on two straight lines identical with direction of feed, so each round trip of ram need only be given the workpiece feeding once.When ram (9) is whenever finished a round trip, driven wheel (6) also drives travelling gear (12) makes cam (13) rotate a circle, the projection of cam (13) pushes the roller (14) of ratchet connecting rod (15) and then stirs ratchet (17) action once by ratchet holder (16), ratchet (18), realizes primary feed.

With reference to Fig. 2, be the schematic diagram of the knife rest of the utility model embodiment 1, two clapper boxs (4), clappers (20) and folder tool rest (3) are arranged on planker (5), can press from both sides a cutter (1) on each folder tool rest (3), fastening by trip bolt (2).

With reference to Fig. 3, Fig. 4, be the schematic diagram of the knife rest of the utility model embodiment 2.Two clapper boxs (4), clappers (20) and folder tool rest (3) are arranged on the planker (5), said folder tool rest (3) is a square member that is fixed on the clappers (20), a folder mouth (22) that clamps cutter is respectively arranged on its four jiaos, four cutters (1) are fastening by 8 trip bolts (2), there is a circular hole at folder tool rest (3) center, and the axle (23) that is placed in clappers (20) is last and fastening with fastening nut (21).In the work,, convert adjustable cast iron planes to, need only become flexible nut (21) as force plane as the different workpiece that require of need planings, rotating clip tool rest (3) then, fastening nut (21) can be finished conversion again.
